Extract numeric values from your UI using integer and float response schemas. This is essential for reading counts, prices, percentages, and other numeric data.

​
Basic Usage

from askui import VisionAgent

with VisionAgent() as agent:
    agent.tools.webbrowser.open_new("http://www.example.com")
    agent.wait(3)

    result = agent.get("How many headings do you see?", response_schema=int)
    print(f"result: {result}")

​
Best Practices

  1. Specify Units When Relevant: Be clear about what units you expect 
    # Good - clear about units
price_dollars = agent.get("What is the price in dollars?", response_schema=float)
weight_kg = agent.get("What is the weight in kilograms?", response_schema=float)

# Less clear
price = agent.get("What is the price?", response_schema=float)
  2. Validate Numeric Ranges: Check if values are within expected ranges 
    percentage = agent.get("What is the progress percentage?", response_schema=float)

# Validate percentage is between 0 and 100
assert 0 <= percentage <= 100, f"Invalid percentage: {percentage}"
